A web-based operator verifies and manually changes the form’s data and edits any invalid entries. Once all the forms are complete for the day, MBS middleware kicks in to transform all of the form’s data to EDI formats using HL7 standards. The insurance providers using web based query screens can view all of the forms. BCBS of North Carolina, Prudential, and Aetna were some of the major clients of this system.
